Protective relaying performance reporting

This paper reports on the performance of protective relaying systems which is an issue within the electric power industry which has received inadequate attention. The wide variations in relaying types and styles and applications, as well as differences in company structures and industry terminology, have hindered the adoption of a standardized system for the evaluation of protective relaying system performance. Such a system, if adopted by a significant portion of the industry, would provide suppliers and users better information with which to improve the product and its application and operation. The Protective Relaying Performance Criteria Working Group of the IEEE Power System Relaying Committee has generated this paper for the purpose of defining a standardized protective relaying performance reporting system.
